Hello,

I am using runtime version v2.0.50727 of IEvolution, 4.4.1.0 version. In order to support the display of PDF images, I have used the ImageMagick plugin in my _load method:

bool loaded = HiComponents.IEvolution.MiscPluginsImageMagick.RegisterPlugin();

When I fill in PDF files from my folder, I use the following:

ieMulti1.ImageList.FillFromDirectory(formsPath,true,false,"pdf");


The PDF images are displayed in my ieMulti1 control. However when
I scroll down, there is flickering on the screen. This might be something in the internal workings of the ImageMagick conversion/plugin.

Is there any way to eliminate these artifacts?

Thanks
Mike

Yes, other images such has TIF, JPG and BMP load okay with no flicker. I think it has to do with the PDF rendering through the ImageMagick. I will confirm this tomorrow.

Hi Mike

Unfortunately this does not seem to be easily fixable due to the way the loading is handled by ImageMagick.
